Application mea March '9,

To all whom it may concern.'

Beit known that I, CARI. Bnnnn, a citizen of the United States, andresident of the city of Detroit, county of `Wayne, State of Michigan,have invented certain new and useful Improvements in Oil Filters, ofwhich the following is a specification, reference being had to theaccompanying drawings.

.It is the primary object of my invention to provide means, associatedwith a screen device, employed on the end of an oil line such as isusually placed in the crank case of an internal combustion engine,whereby oil rmaybe allowed to pass from the crank case or likereservoirs, into the end .of the oil line.

It is a further object of my invention to provide such a device of cheapand economical construction.

yWlth the above and other objects in view,

my invention consists of the arrangement,

combination, and construction of the various arts` of my im roveddevice, as described 1n the specification, claimed vin my claims, andshown in the accompanying drawings,

in whichz' Fig. 1 is a sectional view of an engine crank `case showingmy improved device in section, as well as a conventional oil pump inelevation. f

Fig. 2 is a sectional view taken on line 2\.2 of Fig. 1.

Fig. 3 is a sectional view taken on line 3-3 of Fig. 1.

I have shown an engine cranks case 10, within which is ositioned aconventional oilv pump 11, having a conduit 12, leading therefrom andconnecting with a vertically disposed conduit 13, the lower end of whichis positioned near the bottom of the crank case.` v

Positioned on the end of the conduit 13 and secured by means of a pin 14is a spider consisting of a center plate 15 having diverging arms 16,over which is disposed a v screen 17. A ring 18joins the ends of thearms 16. c

Positioned intermediate the ends of the conduit 13, is a second spiderconsisting of a 4center plate 19 having diverging arms 20 joinedtogether at their ends by a ring 21. A screen 22 is provided over thearmsx20. The rings 21 and 18 abut each other as shown in Fig. 1, leavingan intermediate 1925. Serial No. 14,051.

space 23 between the arms 16 and 20, and the screens 17 and 22. l

A coil spring 34 is provided in this space encircling the conduit 13,the bottom of which spring is adapted to bear against the top of the/late 15, and to be held in place by the struck up lugs 25 on the plate.-A valve or cap 26 is provided on the. top of the spring 34, the springbearing against the shoulder 27 on the valve. The valve 26 is thus heldagainst the plate 19 by the pressure of the spring 24.

Suitably secured In the normal operation of my improved device, oil inthe crank case will be drawn by the suction of the pump 11 thru thescreens 17 and 22, the openings 31, and conduit 13, to be passed on bythe pump for the suitable lubrication of the various parts. Should thescreens 17 and 22 for any reason become closed so that oil may not passthru them to the apertures 31, the suction from the pum will cause thevalve 26 torunseat lagainst t e pressure ofthe spring24, and the oilwill pass thru apertures 32 in the plate 19 over the valve 26, and thruthe apertures 31 for lubrication in the usual manner. 4

It will be obvious that various changes may be made in the arrangement,combination, and construction of the various parts of my improved devicewithoutdeparting from the spirit of my invention, and it is myintention'to cover, by my claims, such changes as may reasonably beincluded within the scope thereof. v What I claim is:n

1. In combination, a conduit having an opening therein, a screensurrounding said opening, an iimperforate member spaced from and housingthe to screen, suction means or drawing fluid through the conduit, anormally closed valve adjacent to said `screer'i ada ted-to rmt accessof fluid lto said conduit throug said to the conduit 13 above the screen22 is a circular shield 28 having a and side of said.

opening when unseated, and said suction means being adapted to open saidvalve in the event of clogging of said screen.A

2. In combination, a conduit having an opening therein, a screensurrounding said opening, a plate around a portion of said conduitspacing a portion of saidy screen from the conduit, said plate havingopenings therein, a valve within said screen normally held against saidplate to prevent passage ot' Huid through said openings to the interiorof said screen and suction means for drawing iuid passing through saidscreen through said conduit, said suction means adapted to, unseat saidvalve and permit passage of fluid through said openings to said conduitopening in the event of clogging of said screen.

23. In combination a conduit having an opening therein, a screensurrounding said opening, a plate around a portion. of said conduitspacing a portion of said screen from vthe conduit, said plate havingopenings therein, avalve Within said screen normally held against saidplate to prevent passage of fluid through said openings to the interiorof said screen, an imperforate member spaced from and housing the topand sides of said screen, and suction means for drawing Huid passingthrough said screen through said conduit, said suction means adapted tounseat said valve and permit passage of fluid through said openings tosaid conduit opening in the event of clogging of said screen.

4. In combination a conduit having anv opening therein, a screensurrounding said opening, a plate around portion of said conduit spacinga portion of said screen from the conduit, said plate having openingstherein, a valve within said screen normally resiliently held againstsaid plate to prevent i passage of fluid through said openings to thelnterior of said screen and suction means for drawing Huid passingthrough said'screen through said conduit, said suction means adapted tounseat said valve and permit passage of Huid through said openings tosaid conduit opening in the event of said screen becoming clogged.

5. In combination, a conduit having a side opening therein, a platesecured on the end of said conduit below said opening, diverging armsextending from said plate, a ring joining the free ends of said arms, ascreen supported by said arms and ring, a secon'd plate disposed aroundsaid conduit above said opening, diverging arms extending from saidplate, a ring joining the free ends of said arms, a second screensupported by said second arms and rings, said arms being bent and saidrings being arranged in abutting relation to each other.

6. In combination, a conduit having a side opening therein, a platesecured on the end of said conduit below said opening, diverging armsextending from said plate, a ring joining the free ends of said arms, ascreen supported by said arms and ring, a second plate disposed aroundsaid conduit above said opening, diverging arms extending from saidplate, a ring joining the tree ends of said arms, a second screensupported by said second arms and rings, said arms being bent and lsaidrings being arranged in abutting relation to each other, and meansconsistingof a coil spring positioned around said conduit, above saidsecond plate, for resiliently holding said rings in abutting relation.

7. In combination, a conduit having an opening therein, a screensurrounding said opening, a plate around a portion of said conduit,spacing a portion of'said screen from the conduit, said late havingopenings therein, a shoul'dere valve within said screen, a coil springaround said conduit, beneath said valve and bearing against the shoulderthereon to normally hold said valve against said plate to preventpassage of Huid through said openings to the interior of said screen andsuction means for drawing fluid passing through said screen through saidconduit, said suction means adapted to unseat said valve and permitpassage of iui'd through said openings to said conduit opening in theevent of clogging of said screen.
